Apparently others here have seen the same type of beams:
Last night we had a heat lightning storm, and regular lightning too, as a matter of fact lightning hit a fuel tank by a GM plant that had over a million gallons of gas and it was burning all night, may still be somewhat, but anyway........I was sitting outside smoking and I kept watching these "beams" or "orbs" or whatever it was going in a big circle. One main one and occasionally a second one would be in a smaller trajectory path. Sometimes a third one would come and seem to "chase" the main one. It was like those spotlight search light things, or you know how advertisers will beam light from the ground, only they weren't from the ground they were horizontal and the path wasn't fixed, it was somewhat random and changed, It went on for more than an hour.
Unusual beams of light during storm
And This seems to be ongoing, I wonder how many other places around the globe this is occurring.
